Because of: [Terms aggregation | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html#search-aggregations-bucket-terms-aggregation-size)

`size` is `10` by default.

I agree. I was very surprised that the default value is not on this page.

Would you like to send a pull request to fix that?
